Abstract: A Cockcroft-Walton (CW) switching voltage converter is disclosed. This CW switching converter includes a set of capacitors; an inductor coupled between an input voltage source and the set of capacitors; a set of switches; and an N-phase control module coupled to the set of switches. In some embodiments, each switch is controlled by the N-phase control module which is configured to sequentially and periodically effectuate a set of N voltage-conversion phases in a sequence of switching cycles. Note that each switching cycle effectuates a voltage conversion through the set of N voltage-conversion phases, wherein N is the conversion ratio of the CW switching voltage converter. Moreover, the N-phase control module is configured to effectuate a phase transition from a current phase to a subsequent phase when a zero-current switching (ZCS) condition on a given switch is met.

Abstract: Techniques for managing transmission rates for users from each of a plurality of call engines (CEs) distributed on a communications network are provided. A list of users with at least one pending call in a corresponding queue from all other CEs is received, wherein each user's queue has a maximum queue depth calculated, in part, using a capped transmission rate in calls per second (CPS) for each user associated with their queue. It is determined, for each user, a total number of CEs having at least one pending call in their corresponding queue. A current CE transmission rate is calculated for each user by dividing the capped transmission rate for each user by the total number of CEs having at least one pending call in their corresponding queue. The current CE transmission rate indicates a rate at which calls in each user's queue are dequeued at each of the plurality of CEs.

Abstract: One embodiment of the present invention relates to an avalanche safety system including an inflatable chamber, activation system, inflation system, harness, and a container. The inflatable chamber is a three-dimensionally, partially enclosed region having an inflated state and a compressed state. The inflated state may form a particular three dimensional shape configured to protect the use from impact and/or provide flotation during an avalanche. The inflation system is configured to transmit ambient air into the inflatable chamber. The harness may be a backpack that enables a user to transport the system while engaging in activities that may be exposed to avalanche risk. The container is releasably coupled to the harness including a coupled and a separate state. The container independently includes a container chamber that is selectively enclosable by a container opening. The releasable coupling between the container and the harness may include a periphery zipper type coupling.

Abstract: One embodiment of the present invention relates to a method for inflating a chamber within an inflatable avalanche safety system. The method includes providing an inflatable avalanche safety system including an inflatable chamber; receiving a user-triggered action intended to activate the avalanche safety system; transmitting ambient air from an external region to within the inflatable chamber; and inflating the inflatable chamber entirely with the transmitted external ambient air to a particular internal pressure and shape configured to protect the user from burial during an avalanche. The transmission of ambient air within the inflatable chamber may be accomplished with a fan or an electrical component.

Abstract: One embodiment of the present invention relates to a user based carrying system capable of independent transportation of a load including a hip-based user attachment system. The carrying system includes an enclosure member having an internal region encased by an internal surface. A user attachment system releasably secures the carrying system to the user for independent transportation without requiring muscular engagement. The user attachment system includes a hip attachment system with a dorsal articulation member and a strap member. The dorsal articulation member includes a front and rear member three-dimensionally moveably coupled to one another. The rear member is coupled to the enclosure member and the front member is coupled to the strap member. The three-dimensional moveable coupling between the front and rear members includes three restricted degrees of freedom configured to efficiently absorb corresponding user hip movements and directly support other user hip movements.
